1 My invention relates to pop-upvalves for waste'pipes of bowls, tubs and containers of thelike 'nature and more particularly to popup; valves of thetype which are adapted tobe ,jg operated by means positioned externally of the liquidy container.

My invention contemplates the provision of arpop-up valve comprising a sleevewhich isreadily removable from'the drain pipe with 2o which itis associated' and which presents un'-` obstructed drainagetherethrough. j Another object of my inventiony is to pro` vide a pop-upvalve'having a sleeve for permitti'ng free andv f unobstructedV drainage le therethrough, said sleeve being readily; rei movable from the drain pipe with which it is associated 'and f adapted 'to be "actuated through the* agency of anindependent-annularl'me'mber positioned within the drain zopipe.' 'HA further object of myinvention is to pref clude, .as faras possible, the removal through theft or inadvertencegbfdrainage valveparts by providing a pop-up valve Comprising a drainage sleeve which lmay be readilyr inserted within a drain pipe'and which is' pro- .vided with a way formed 'in the outer "periphery thereoffor'co-operating with a locking pin's'o asto necessitate partial rotation of 3mi/the sleeve'in-orderrto completely insert or remove vthe sleeve. 1 f -i Aj'still further objecto'f my invention is to l Y provide a pop-up valve,y as above set forth,

having a sleevey which will permitthe `free drainage of waste mattertherethrough and which maybe Vreadily inserted or'removed'by i a personI familiarA wi'th'alocking combina- ,tion associated with the sleeve, said locking f combination being such/that the Yinstallation 40 thereof does notnecessitate the perforation of any portion of thedetachable sleeve.

. v These and other objects-will belmore ap- .p'arent from the following detailed descrip- @tion when considered in connection with the accompanying drawings,wherein- Y conventional basin or bowl which is equipped ,with a pop-up valvekembodying features of my invention; i i `g 1.1igure-2 is anenlarged:vertical sectional Flgure 1 lsa vertical sectional viewof a view1 ofthe pop-up valvey disclosed in Fig-A um n --^Figure 3 isa horizontal sectional view taken transversely of the valve along the line 3 3 of Figure2; and f lFig/:ure 4L is a detailed elevational view of the detachablesleeve, said view being shown primarily to disclose/the nature of the way orlocking groove rformedyin the periphery of said sleeve. v Referring now to the drawing wherein like numerals have been employed to designate similar parts throughout the various figures, it will b'e'observedthat I have disclosed, for the purpose of illustrating'ar practical application' of my improved pop-up valve,a conventional basin or .bowl 2. Over-flow water fromthe basin 2 may pass through an lopening '4 in' said basin into a chamber 6 which-will direct such over-flow water to the central portion of the basin at W ich position myfvalve is installed. y L

By referring to Figure '2; itwill be seen that I .provide a fixed sleeve member 8` which isy provided with a usual valve seating flange 10 at the upper end thereof. The lower half y of the fixed sleeve member-"8 is threaded to receive a clamping ring 12 which serves'to securey the fsleeve to' the basin 2. Threaded to the lowermost extremityfof the sleeve Sis fixed sleeve member S'is another'sleeve' 16.1y Thissleevel is provided "so -ajsuitablefdrain coupling 14 and vertically slidable within the atits upper end with a cap 18 which is adapt- -ed to seat against the "flange 10 when said l jsleeveis completely lowered within the fixed .sleeve member" 8. formed within the' sleeve 16 to permit the iiow Drain openings 20 are of waste matter through the'sleeve from the basin 2` when said sleeve occupiesl theV elevated position shown bythe dottedlines in Figure 2 VItwill be observed that thek sleeve 16 isfimperforate and presents avsmooth unobstructed surfacefbelowthe drain openings 20 so as to permitthe 'free drainageof material `therethrough and that the space between the outer surface of said sleeve and they inner surface of companion fixed sleeve 8 is very small ,so-as to prevent the accumulation of foreign mattersuch as soap and the'like. .Y y,

The lower extremityof the sleeve 16 ter- Y minates within the coupling 14 adjacent the upper portion of an annular sleeve lifting means 22. This lifting means 22 is vertically slidable within the coupling 14 and is provided with anjannular groove 24 which accommodates the inner extremity of alever 26. This lever 26 passes through a laterally extending portion 28 or the coupling v14 and is provided-with aball-ilikeportion BOwhichf is housed within closing `vcap 32, fthe'nsual packing gland being employed to provide al Water-tight ft JOlQlAeVQIl? the escape of water through theY laterally extending portion 28.

of the coupling 14. ln response to the movemerit of fthe lever v26,'the lifting means 22 will be shifted vertically within the coupling 14i`and thereby elifeot the eleva-tion of the re-V movable sleeve 1'6. It will b'elnoted'thatthe opening within the annular lifting memlbei 22 is greater in ydiameter :thanfthefopening within the 'sleeve V.16, therebyfinsuring the free and nobstructedow of waste materialv from the sleeve 116 through Ythe lifting member. y A Y It--i'svery *desirablet'o have the sleeve 16 construfctedso as vtobereadily detachable from and insertable within the` fixed sleeve -8,but it isequallydesirahleto provide means 'Y will vbe `apparent that in order to properly jinsert the sleeve 16 within'the sleeve i8, the

`lower vertical p'orti'onjof the groove 34,5m1`1st 'lirstb'e broi'iiglt into registration' with the il-oekinl'gpi-n or 'member 36.y The sleeve mayy j tlrenb'e Elowered 'until the horizontal `portion @sleeve mustbe partially rotated ina clock-y wise direeti'om as 'viewed :in Figure 3,' until the upper 'vertical 'portion ofthe groove registers with" the locking-pin; The f sleeve 16 Vmay then 'be' 'completely lowered within the companion sleevje8`so as to occupy the' "position disclosediii'flli'gure 2. Inre'mov'ingthe :"sle'eve' 16 it if'sfo'nly necessary to 'reverse tlife movements guet described in eonneeten 'with fithefinsertion ftheref.' In "this y'eonn'eeti'on it s' *Leibe noted that Tprevide a-lewerfextended portaient@ fthe yupper Avertical sect-ien er thfe numeral -138", Figure l4,- and obviously if `the' sleeve 16 'iswithdrawn vertealfly'by a iperson not amiliarfwi-th'the joggedtr 'bayonetshaped construction of the groove 34, the e horizontal portion of the groove will 'be moved past the pin 361with` the result that 'i the extended portion 38 of the groove will beV movedinto association Vwith said pin.VV In other words, the sleeve 16 can only be completely withdrawn by elevating said sleeve untilthe horizontal portion of the groove34 is carriedwinto registration with the pinh36 Y at which `point'thejsleeve must be partially rotated in ordert'o permit the continued upward movement thereof. Obviously, ways or grooves of varied forms may be used without departing from the spirit and scope ofV my invention. The l ayonet-shaped groove which I'have disclosed in the drawing,how.f

ever, illustrates V'one type of 'groovewhich necessitates verticaliand "angular displace# ment 'of the'sleeve in orderito completely remove the same andk thereby presents a very practical means for avoiding -thelin'advertent removal of -`such parts; e i e By providing means such "as the annular elevating means 22 operable:independently of the. sleeve, I vhave avoided the 'necessity this vconstruction the sleeve16 is verylsimpl'e in construction andmay be readilyr'emove'd for e lpurposes of repair 4'ko'r replacement with i little diflicul'ty. Also, "myfinvention provides avery economically"constructedand 'effii ciently` 'operable pop-up valve whichimay be readily, althoughV n ot inadvertently, fre? moved from-the operative"association with e 'adrain pipe. vAs"hereinb'efore suggested, my
